ARTHUR EDWARD THOMAS, OF LONDON, ENGLAND.

SPANNER.

Application filed November 13, 1924, Serial No. 749,703, and in GreatBritain November 15, 1923.

This invention relates to spanners and refers particularly to such toolsas are intended to be employed in connection with cycles or the likevehicles furnished or provided with free-wheel mechanism. Suchmechanisms are furnished with a screwed sleeve having on its outer end aslot or slots to facilitate their manipulation.

The chief object of the invention is to provide an improved tool forengaging the said slot or slots so that the free-wheel may expeditiouslyand easily be removed from, or replaced on, the wheel-hub or spindle.

A further object of the present invention is to combine in a singletool, spanner-like or gripping parts for manipulating nuts and the likenot only connected with'the freewheel gear but on other parts of thecycle or the like whereby a single tool can replace the usual spanneroutfit required for such vehicles.

' According to the present invention the spanner or tool, whichconveniently constructed from sheet metal of appropriate thick ness,comprises a body portion having enlargements at either end, one of whichis provided with two teeth, studs. lugs or projections locateddiametrically opposite toeach other relatively to a central opening andadapted to engage with slots in the sleeves of the free-wheel mechanism.These teeth or the like may be formed integral with the spanner or beattached to or mounted therein in any appropriate manner, and thecentral opening allows the tool to be passed onto the end of the spindleon which the freewheel is mounted.

Surrounding the central opening is an outstanding ring or flange whichis adapted to fit into or within the sleeve of the freewheel and theteeth are situated at the outer periphery of this ring or flange.

This end or head of the tool is conveniently approximately circular andat one portion near its outer periphery are situated two pins adjacentto which the outer periphery of the head has a curved part so that thesepins can engage two holes in the end plate of the free-wheel mechanism.

In the outer periphery of this head also are cut at suitable points,jaws adapted to engage square, hexagon or other nuts. A rectangularprojection is also furnished on the head to serve as a screw drlver.

Further, one or more box spanners are prolvided in the body or leverportion of the too In the other end'of the tool orthe part whichnormally serves as the handle there is provided a slot having portionsof different diameters and these diameters are adapted to fit and grip,for example, the back cone, the front cone and the pedal-crank cone. r

. Referring to the accompanying drawings. Fig. 1 is a face view. I IFig. 2 is a side elevation and Fig. 3, a section on the line 3-3 ofFig. 1. I i

In accordance 'with this embodiment of the invention there is formed atone end of the body part A an approximately circular head A furnishedwith a central opening.

provided in the outer end or edge of a sleeve of the free-wheel.

'These teeth or studs B, as already stated, maybe formed integral with"the head A of the tool; in the present example however they are formedintegral with a cone C which fits within and is secured in the centralopening in the head A and projects from the face thereof opposite to theteeth or pins B.

Formed integral with this cone C also is a ring or flange D. Thisflange-is of such diameter that it fits within the sleeve of thefree-wheel and is of such depth that in engaging with the innercircumference of the sleeve it gives a bearing and steadiness to thetool when the teeth B are in position. The teeth B are situated at theouter periphery of the ring D and are integral with it, they passthrough slots cut in the central opening in the head A.

The interior of the cone at C is formed to accommodate the cone portionof the hub disposed within the sleeve of the freewheel and it is formedso as to fit over the shoulder upon the spindle of the hub carrying thefree-wheel, and the end of this spindle passes through an opening C inthe cone.

The opening C is preferably hexagonal and can serve as a box spanner,such for example as is required for the nut of the back spindle of thecycle.

Around the periphery of the head A,- spanner jaws may be provided bycutting suitable slots in the material. In the example illustrated threesuch openings are provided. The opening-E is large enough to fit thenuts of the cotter pins used on the cycle and the jaws E and E areadapted to grip respectively the nuts of the chain wheel, the nuts ofthe bottom bracket, and the nuts of the brakemechanism.

Two pins F F are secured to the head A and project from the same facethereof as the teeth B. These pins are situated near the outer edge ofthe head A and the periphery of the head A between these pine is curvedor recessed at F to fit onto or against the sleeve of the free-wheel sothat the pins F F can engage with pin holes provided in the end of thefree-wheel casing, thus providing a pin-spanner for this plate.

Gr represents a rectangular projection Which may be formed integral withthe head A or attached thereto in. any appropriate manner and thisprojection is somewhat wedge shaped or tapered to form a screwdriver.

At the other end of the body A is formed an enlargement or head A andaxially of this head is formed a slot which is of different widths ordiameters throughout its length. The outer portion II of this slot isWide enough to form jaws adapted to grip spanner-Wise the back bone andpedal-crank cone, while the inner portion H is adapted to engage thefront cone in a similar manner.

Additional box spanners may be provided by forming properly shaped holesin the body of the spanner. In the present example two hexagonal holesJ, K are provided and these may serve for example for use on the frontspindle or other nuts.

What I claim is r 1. In a spanner for the free-Wheel of a cycle or thelike, the combination of a plane body portion, an annular ring or flangeon one face of said body adapted to enter a sleeve to position the faceof the body portion against the end face of said sleeve, and a pairof'teeth projecting from the same face of said body and adapted to enterrecesses in the end of said sleeve. 7 I V 2. In a spanner for the freewheel of a cycle or the like, the combination of a plane body portionhaving an opening therein for the passage of the wheel spindle, twoteethprojecting from oneface of said body portion at opposite sides of saidopening adapted to engage in recesses in the end face of a sleeve. and aring or flange on the same face of said body portion concentric withsaid opening, said teeth being located beyond the periphery of said ringbut within the perimeter of said body portion.-

3. In a spanner for the free-wheel of a cycle or the like, a bodyportion having an opening therein, a conical member secured in saidopening with itsbase portion projecting through said body to form aringor 'ange at one side of said body, andafpair of teeth formed at the baseof said conical member adapted to enter recesses in the end face of asleeve of a hub positioned in said conical member.
